The original throttle body from my 99 z28 is for sale. I replaced it with a ported throttle body and don't need this one anymore. Worked perfectly. NO SENSORS, they were transferred to my ported throttle body. Would be a good core if you wanted a ported throttle body and still want to keep your original. $50.00

Also have the original steel driveshaft from the same car. 50k miles excellent condition. I replaced it with an aluminum one. $50.00

All prices are plus shipping. If you're local I might consider trades for either.
